I had a major problem with a root canal treatment that my regular dentist had tried to do. I contacted Dr. Katz's office and everyone-from the staff to Dr. Katz is terrific! He not only corrected the root canal with very minimal discomfort, but the tooth is 100% fine now. He makes you feel so comfortable and is not only extremely knowledgeable, but very friendly and gentle. I would highly recommend him to anyone needing a root canal. He's the best!
